T0 all whom it may concern:

Be it known that I, WILHELM SCHTZ, a citizen of Germany, and residing at 19 Sohlossstrasse, in the city of Dusseldorf, Germany, have invented certain new and useful Improvements in Masonr'y Coat Holders for Mortar and the like, of which the following is a specification.

This invention has reference to sheet metal carriers forthe exterior coatings of masonry, generally designated by various names as rendering, laying or pricking-up coat, slipped coat, finishing coat, screeding, rough casting, whitewash, and the like, and it is intended to overcome thje drawbacks and inconveniences heretofore encountered with sheet metal carriers of the kind referred to, and to greatly increase the adaptability and durability of such carriers. According to 'the previous art either perforated or unperforated sheets were utilized for the purpose in question. With a view of increasing the adhesion of the coat to the sheet metal the unperforated sheets have heretofore been bent either entirely or in part, so as to constitutedoye-tail portions, or similar members have been connected to the sheets by riveting or such members were provided by cutting out and suitably bending parts of the sheet. Now all. such detached elements are stretched and distorted upon being subjected to tensional stresses and to strains, and are liable to be sheared olf, and on account of the reduction of lthe operative surface produced by the formation of these members they entail a great consumption of constructional material. Furthermore, plain metal sheets are considerably weakened by the perforations and are likely to be leaky and present leaks, even in case the perforations are closed by rivets, and this is particularly the case with thin sheets which can only be cold-riveted, and whenever they are submitted to variations of shape.

My invention provides for a novel carrier in which these difficulties are avoided by doing away with perforations and cuts, and leaving the sheet entirely uninjured, so as to cause it to preserve its full supporting capacity and tightness irrespective of all alterations of shapes. The novel carrier moreover, is superior to the sheet metal carriers referred to as regards economy of manufacture and ease and conveniencezofA employment. v

Upon the accompanying drawing I have shown by way of example and in a conventional manner a sheet metal carrier embodying the principles of my invention in Figure 1 in cross section on the line 11 of Figure 2 with a diagrammatic indication of the masonry. Figure 2 is| an elevation of the carrier, and Figure 3 is a modification in which the carrier takes the shape of a pipe or of a hollow pillar.

In the drawings a is the sheet metal plate b are the holders of any suitable configuration, for instance, dish shaped, though my invention is l"by no means limited to this partcular form of holders which may comprise smaller strips or pieces of sheet metal b, d or the like which are secured to the main sheet a by welding o-r the like rWithout perforating or otherwise weakening the main sheet, and which, with the ex.. ception ofthe point of attachment c only are protruding from said` main sheet. The said small sheet metal pieces b, d may be preferably secured to the main sheet of any suitable shape and configuration by an elec* tric spot welding process or the like by f means o-f which they are attached at one point only. If desired, such holders may be secured on both sides of the main sheet. In the latter case the holders for the coating are most conveniently aranged opporsite each other, and are connected to the mainsheet by one single Welding point c.

It is obvious that by proceeding in this manner the main sheet is not injured nor weakened nor is it liable to present leaks. It should be understood, of course, that the invention is'by no means restricted to the particular shapes and configurations and steps of proceeding herein shown and described, but the invention is broad enough to admit of modifications and changes within the scope of the claims hereunto appended.

I claim l. A sheet metal carrier for masonry and the like, comprising a mainsheet metal y sheet metal body With their convex faces lying in direct abutting contact therewith the abutting portions of the main sheet metal body and concavo-conveX sheet metal members being imperforate and integrally joined.

2. A sheet metal carrier for masonry and the like, comprising a main sheet metal body, and a plurality of parallel, spaced unitarily formed linear strips of sheet metal disposed upon a surface of said main sheet metal body, each strip being transversely of concavo-convex form and having its c0n Vex face lying in direct abutting contact With said surface of the main sheet metal body, thev abutting portions of the main sheet metal body and the sheet metal strips being imperiorate and integrally joined.

3. A sheet metal carrier for masonry and the like, comprising a sheet metal body of cylindrical form, and unitarily formed transversely dished linear sheet metal strips having their convex faces lying in direct surface contact with a surface of said cylin* drical body and joined thereto.

WILHELM SCHTZ.
